I think one mistake we all make is putting our Anti-cor of choice on , while the blocks are still too hot........and would buy into this....for VERY long term storage.........The " Pores" in Meehanite iron are pretty open , at 300 degrees F......and no clue here as to at how low a temp they close.
I've been using that NAPA Lube Gard, when I use anything at all..................that being the High Summer months, when the evaporative cooler is running in the shop....it can play hell with the lathe bedways , and other machine surfaces, too.
Over on Hamilton's Cast Bullet list.......they discussed some kind of " Vapor Chip".......put this in a baggie, with yer' mold blocks.......................I'm scared to death of some of the chemistry used in the new, and better products......molecules with a name one paragraph long, and such.....TC 1000 bore butter was what I used to use, and it seemed to work OK.....A good soak, in Hardware store Acetone, or Laquer thinner, is not a bad idea, IMHO, prior to gettin' the ball rolling, after storing them , with an Anti-cor, of ANY stripe.
